I had this treatment twice previously done by dermatologist doctors and never had problems with that. My experience with Nina unfortunately was not good. She did not leave numbing cream long enough about 7min only so the injections were painful. My armpits was in pain for 7 days after the treatment. If treatment provided correctly it should be no pain afterwards.I texted her about the issue. She ignored completely. My advice to all use only qualified dermatologist doctors! Avoid this venue
